Installing all the water pipe work on the lpg conversion R75 and encountered a first ---- a normal worm drive "Jubilee" style hose clip but with a left hand thread --- just so odd and unatural.

I have a few boxes of odd hose clips from various sources so I don't know where it came from must have been from from Ned Flanders left handed shop in the mall

ha ha thats weird! i can't think of a single use for them, as in why they would specifically need to be left hand threads

Thats ok, just use a left handed screwdriver

the intercooler pipe on my nissan powered indy is left hand thred.
